He has already been banned once this season, for raising his hands to Arsenal defender Laurent Koscielny in September, and has been booked 11 times.

Even worse news though for a Chelsea team struggling for goals and quality is that Belgian star Hazard, who has had an injury plagued campaign, could now be sidelined for as long as four weeks with a recurring hip problem, the club fear.

Hazard, who has scored only two goals all season, has been struggling with the injury for some time and has been worried that it has not gone away.

The 25-year-old has been heavily criticized for his performances, but sources close to the player say he has been deeply concerned about the first serious injury of his career.

Star players Antonio Conte could bring to Chelsea

Antonio Conte has been announced as Chelsea's new headcoach so Express Sport takes a look at some of the star players he could bring to Stamford Bridge

Hazard is expected to move on in the summer, with both Paris St Germain and Real Madrid watching developments.

While Costa, sent off in the FA Cup sixth round defeat at Goodison Park on Saturday for the first time in his Chelsea career for picking up two yellow cards, was charged on Monday with misconduct by the FA for his actions after being dismissed.

The Spain striker was cleared of appearing to bite Everton’s Gareth Barry during the incident, but after being sent off by referee Michael Oliver he reacted furiously, remonstrating, appearing to shouting at the official and even at one stage seeming to spit at his feet.

The FA said: “It is alleged that Costa’s behaviour, after being shown a second yellow card, amounted to improper conduct.”

Costa has until Thursday to respond to the charge, which will go before a disciplinary commission, but if found guilty is likely to be hit with another one game ban on top of the one he has already picked up for the dismissal.

But the controversial Spaniard could even face another ban, with the FA asking him for his observations on allegations that he made an obscene gesture to Everton fans at half time.

If charged and found guilty, that would be another one game ban.

Meanwhile, Italy coach Antonio Conte is expected to move a step closer to becoming Chelsea’s new manager when he meets the Italian football federation - the FIGC - on Tuesday to discuss his departure after the Euro2016 finals.
